Question

22.Which statement best describes the relationship between receptive fields, density of mechanoreceptors, and two-point discrimination? Question options: A) The smaller the receptive field, the higher the density of mechanoreceptors, the smaller the two-point discrimination. B) The larger the receptive field, the higher the density of mechanoreceptors, the larger the two-point discrimination threshold. C) The smaller the receptive field, the higher the density of mechanoreceptors, the larger the two-point discrimination threshold. D) The larger the receptive field, the higher the density of mechanoreceptors, the smaller the two-point discrimination threshold.

explantion would be helpful, thank you!

Explanation / Answer

Two point discrimination is the ability to distinguish two points applied simultaneously. There is a direct relationship between receptive field, density of mechanoreceptors and two point discrimination. Smaller the receptive field, higjer the density and smaller the two point discrimination. Option A is correct.
